IGMP proxying configuration example
Network requirements
As shown in Figure 28, PIM-DM runs on the core network. Host A and Host C in the stub network receive
VO D i n f o r m a t i o n s e n t t o m u l t i c a s t g r o u p 224 .1.1.1.
Configure the IGMP proxying feature on Router B so that Router B can maintain group memberships and
forward multicast traffic without running PIM-DM.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 28. (Details not
shown.)
2. Enable IP multicast routing, PIM-DM, IGMP, and IGMP proxying:
# Enable IP multicast routing on Router A.
<RouterA> system-view
[RouterA] multicast routing
[RouterA-mrib] quit
# Enable PIM-DM on GigabitEthernet 2/1/2.
[RouterA] interface gigabitethernet 2/1/2
[RouterA-GigabitEthernet2/1/2] pim dm
[RouterA-GigabitEthernet2/1/2] quit
# Enable IGMP on GigabitEthernet 2/1/1.
[RouterA] interface gigabitethernet 2/1/1
[RouterA-GigabitEthernet2/1/1] igmp enable
